PROBLEM TO BE SOLVED: To provide a shelf board which is easily handleable and keeps a stable height adjustable. SOLUTION: A shelf board structure 11 keeps a shelf board 41 by frame bodies 51 and includes pressing mechanisms 10 in both ends of a supported material 40 taken as the shelf board 41 (A). Eccentric members 20, 20 including decentered rotary shafts are rotated so that both ends of the supported material 40 exert pressing action on left and right frame bodies 51, 51 taken as abutment objects 50 to be fixed thereto as the shelf board 41 (B). Through this method, the shelf board 41 can be easily fixed at the arbitrary height desired by the frame bodies 51. COPYRIGHT: (C)2008,JPO&INPIT
